Dance class

Hi,
I'm trying to create a simple database for info for dance class students
that includes mailing addresses and class info. Most are children, so I
need the parent names. A few parents have two or three children in a dance
class. Some students are adults. I think I need a parents table AND a
students table otherwise I'm entering duplicate information (addresses etc.)

Two students are also instructors but I think I can use a Yes.No field for
this. I can't get my head around how I link them.

What comes first, the parent table or the students table. Most are children
if that makes a difference.

Any help is appreciated.

Nancy
